Detailed Description#

class PySide6.QtWidgets.QColormap(colormap)#
Parameters

colormapPySide6.QtWidgets.QColormap

Constructs a copy of another colormap.

PySide6.QtWidgets.QColormap.Mode#

This enum describes how QColormap maps device independent RGB values to device dependent pixel values.

Constant

Description

QColormap.Direct

Pixel values are derived directly from the RGB values, also known as “True Color.”

QColormap.Indexed

Pixel values represent indexes into a list of available colors, i.e. QColormap uses the index of the color that most closely matches an RGB value.

QColormap.Gray

Similar to Indexed, pixel values represent a list of available gray tones. QColormap uses the index of the gray tone that most closely matches the computed gray tone of an RGB value.
